Embodiment Construction

[0053] A method for transmitting digital message is realized as the following.

[0054] An generating matrix of operations with k rows and n columns is formed, said matrix is produced using a k.times.k matrix with operations g.sup.0 at its diagonal and operations g.sup.1 at other positions and with a k.times.m additional matrix, which is added from the right to a k.times.k matrix and non-repeated rows of which are formed as sequences of operations g.sup.1 and g.sup.0 or operations g.sup.1 and g.sup.2, chosen from any possible sequences, including not more than (m-2) operations g.sup.1. It's possible, also, to use an generating matrix of operations, produced with a help of said generating matrix of operations by rearranging its rows and / or columns. The resulting generating matrix of operations is a matrix, formed not of numbers, as usual matrixes, but of records, recommending to produce a corresponding operation in situations, when a corresponding element of an generating matrix of oper...

Abstract

The invention relates to telecommunications, in particular to methods and means for transmitting digital messages and can be used for transmitting information through wire channels and telecommunication channels using electromagnetic waves. The use of said channels is simplified by excluding multiplication and division operators from a coding and decoding process. Said invention makes it possible to transmit any messages from elements of Abelian group including code words whose elements are matrixes, polynomials, numbers of mixed-base notation and nonpositional notation. The codes based on the inventive rules pertain to the class of systematic linear block codes. The inventive system for transmitting a digital message comprises an encoder (1), a modulator (2), a transmitter (3), a receiver (4) a demodulator (5) and a decoder (6).

Description

[0001] This invention relates to telecommunications, in particular to methods and means for transmitting digital messages, and can be used for transmitting information through wire channels and through telecommunication channels using electromagnetic waves.DESCRIPTION OF THE PRIOR ART[0002] A method for transmitting digital message, consisting of additive Abelian group elements, is known. This method comprises consequent steps of: encoding digital message, its modulating and its transmitting in a communication channel and demodulating received signal and its decoding [1].[0003] A known system for transmitting digital messages, consisting of additive Abelian group elements, comprises serially connected at a transmitting side an encoder, a modulator and a transmitter and serially connected at a receiving side a receiver, a demodulator and a decoder [1].[0004] Known method and system are rather complicated in a realization because they require to use four arithmetic operations for proc...
